How the calendar works
Rolex calls it the Saros annual calendar. Twelve small apertures sit next to the hour markers. The current month shows as a red rectangle. The date jumps from 30 to 1 on its own. February is the exception. The watch needs one manual correction each year, at the end of February.
The Ring Command bezel sets the functions. Turn it to position one to set the month, position two for the date, position three for local time. The crown does the rest. The click at each position is firm on a genuine watch.
What to check on a used 326939
- Strap condition. Leather on a 2012 to 2015 watch is often replaced. Ask for the original strap and clasp.
- Clasp wear. Everose gold is soft. Deep gouges cost money to refinish.
- Papers and card. A full set sells for more than a watch alone.
- Service history. Ask for the last service date and the invoice.
- Bezel action. The three positions must click and return to zero.
- Month apertures. All twelve must snap at month change, not drift.
Gold cases get polished by sellers. Heavy polishing rounds the lugs and thins the caseback text. Compare photos against catalog images.
Price notes
This reference trades on the secondary market at a discount to its original retail in many markets, because buyers prefer the bracelet versions. Asking prices move with gold spot and with box and papers. Check recent sold listings on a major marketplace before you make an offer. Do not trust a single asking price.
Replica and clone tells
Copies of the Sky-Dweller exist. Most do not run a true annual calendar. On many clones the month wheel is fixed or advances with the date, so all apertures read the same. The Ring Command bezel often turns without changing any function.
Other checks:
- Weight. A gold case feels dense. Plated brass or steel does not.
- 24-hour disc. On a copy it often jumps in steps instead of moving with the hour hand.
- Movement finish. Open the caseback only with the seller present.
- Engraving depth on the rehaut and caseback.
- Cyclops magnification. Genuine is about 2.5x.
A replica with a working annual calendar and a functional Ring Command bezel is rare. Treat a low price on a gold watch as a warning, not a deal.
Buying checklist
- Get the serial and reference in writing.
- Request macro photos of the dial, clasp, and caseback.
- Confirm the bracelet or strap is original to the reference.
- Ask for service records.
- Meet at a watchmaker for a movement check.
- Pay by a method with buyer protection.
